Political Correctness is one of the few current cultural phenomena that really ticks me off. Its intent is to conceal and euphemize distasteful concepts in order to dilute and coverup the fact that certain things are occurring. Its worst form comes when politicians apply political correctness to history -- it is pure and simple revisionism.
Most folks are probably familiar with the maxim that people who refuse to learn from history are fated to repeat it. I submit that those who revise it to suppress potential evils are dooming the whole society to repeating the suppressed activities.
Below the fold I will talk about this more.
